I think you only had one fault...
...and if you are going to continue the series, try fixing the sprites. I don't know where you got the Megaman sprites, but they were really discolored. Try Sprites Inc, they have every single Megaman sprite. Oh, and by the way, the Megaman you were using is not "X". There are 4 of them Mega Man, Mega Man X, Mega Man Volnutt, and Mega Man Exe. You picked the original, from what Capcom tells they aren't related to each other.
